Frequently Asked Questions
Do Lupines come back every year?
Yes! Staircase™ Orange Lupine is a perennial that returns bigger and better each year, dying back in winter and re-emerging in spring.
How do I encourage my Lupine to rebloom?
Deadhead spent blooms promptly to encourage a second flush of flowers in late summer or early fall.
Can Lupines grow in clay soil?
Lupines prefer well-drained, sandy, or loamy soil and do not tolerate heavy clay. If you have clay soil, amend it with organic matter or plant in raised beds.
Do I need to fertilize my Lupine?
Lupines are nitrogen-fixers, meaning they naturally enrich the soil. However, a light feeding in spring with a balanced, low-nitrogen fertilizer can encourage more blooms.
Is Staircase™ Orange Lupine deer-resistant?
Yes, Lupines are generally deer and rabbit resistant due to their slightly toxic foliage. However, no plant is completely deer-proof.
